ClEditor.cpp missing

I ran a search for clEditor.cpp, but it came up empty.

I just went in and made the changes outlined in Phillip O'Shae's resource here, and when I built, I get an interesting error.

Interestingly, when I check out the source folder, I find the source/component/interfaces folder is missing altogether.

Anybody know where I can get clEditor.cpp and clEditor.h?
